About Sonja

Sonja makes it easier to sell your car. We bring several dealers into one auction so you do not have to call around and compare offers on your own. You get competition for your car — without leaving it listed for weeks.

You submit photos and an honest description of the car. We help with what dealers need to bid with confidence. Everything happens digitally, and the car stays with you until you say yes.

The service is completely non-binding. You decide whether to accept a bid or an offer, and you can stop at any time before you say yes.

If you accept a bid, we help with the agreement, paperwork and handover. The goal is a safe sale with as little stress as possible.

We believe selling a car should demand less of you, not more. That is why we build tools and processes that remove unnecessary time without cutting corners on what dealers need to bid.

Less work for you. More dealers competing for your car.
